Casement windows are a popular choice for homeowners due to their versatility, energy efficiency, and ease of use. One crucial aspect of these windows is the window seal, which plays a significant role in ensuring your home stays comfortable and protected from the elements. In this comprehensive guide, we will explore the various types of window seals available for casement windows and provide you with the information you need to make the right choice for your home.
Before delving into the different types of window seals, it's essential to understand their importance. Window seals serve several purposes, including:
Energy efficiency: A well-sealed window prevents drafts and air leaks, helping to maintain a consistent indoor temperature and reduce energy costs.
Noise reduction: Proper window seals can help to block out external noise, providing a quieter and more peaceful living environment.
Protection from the elements: Quality window seals prevent water, dust, and debris from entering your home, protecting your property and belongings.
Enhanced security: A well-sealed window is more difficult to break into, providing an added layer of security for your home.
With these benefits in mind, let's explore the various types of window seals available for casement windows.
Compression seals are the most common type of window seal used in casement windows. They are made from a flexible material, such as rubber or foam, which compresses when the window is closed, creating an airtight seal. Compression seals are highly effective at blocking drafts, noise, and water infiltration, making them an excellent option for most homes.
There are several types of compression seals, including:
Foam tape: This type of seal is made from a self-adhesive foam tape that can be easily applied to the window frame. Foam tape seals are an affordable and straightforward solution, but they may not last as long as other types of compression seals.
V-strip: V-strip seals, also known as tension seals, are made from a flexible plastic or metal strip that is folded into a V-shape. When the window is closed, the V-strip compresses, creating a tight seal. V-strip seals are durable and long-lasting, making them a popular choice for casement windows.
Bubble seal: Bubble seals are made from a flexible rubber or plastic material that features a hollow "bubble" along the length of the seal. When the window is closed, the bubble compresses, forming an airtight seal. Bubble seals are particularly effective at sealing irregular gaps and can be used in combination with other types of compression seals for added protection.
Weatherstripping is another common type of window seal used for casement windows. It is typically made from a flexible rubber or plastic material and is designed to seal the gap between the window sash and frame. There are several types of weatherstripping, including:
Adhesive-backed: This type of weatherstripping features a self-adhesive backing, making it easy to apply to the window frame. It is an affordable and straightforward solution, but may not be as durable as other types of weatherstripping.
Door sweep: A door sweep is a strip of flexible material that is attached to the bottom of the window sash. When the window is closed, the sweep forms a tight seal against the window frame, preventing drafts and water infiltration.
Interlocking metal channels: This type of weatherstripping involves installing metal channels on both the window sash and frame, which interlock when the window is closed. Interlocking metal channels provide a highly effective and durable seal, but can be more challenging to install and may require professional assistance.
Brush seals, also known as pile weatherstripping, are made from densely packed fibers that create a barrier against drafts, noise, and water infiltration. They are typically used in conjunction with other types of window seals for added protection. Brush seals are particularly effective at sealing irregular gaps and can be easily replaced if they become worn or damaged.
When selecting the perfect window seal for your casement windows, consider the following factors:
Climate: Your local climate will play a significant role in determining the type of window seal that is best suited for your home. If you live in an area with extreme temperatures or heavy precipitation, you may require a more robust window seal to ensure your home stays comfortable and protected.
Budget: Window seals are available in a range of price points, so consider your budget when making your decision. While more expensive options may offer greater durability and performance, more affordable solutions can still provide effective protection for your home.
Ease of installation: Some types of window seals are easier to install than others. If you plan to install the window seal yourself, opt for a solution that is straightforward and easy to work with.
Aesthetic preferences: While functionality should be your primary concern when selecting a window seal, you may also wish to consider the appearance of the seal and how it will blend with your window and home's overall aesthetic.
By taking these factors into account, you can make an informed decision and choose the ideal window seal for your casement windows. With the right window seal in place, you'll enjoy a more comfortable, energy-efficient, and secure home for years to come.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.
Why choose the tilt and turn opening method?
Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
